$40.10 trillion ÷ 342.9 million people = $116,954 each

Treasury’s Debt to the Penny put total public debt outstanding at $40,101,500,516,712.09 on September 18, 2026. The Census Bureau’s population clock put the US population at 342,882,536 on September 22. Divided, that is $116,954 for every person, children included.

per person = total debt ÷ population

A household of four carries four shares, $467,816. The number is large because the debt is large; dividing it only makes the scale readable.

September 2026

$40,101,500,516,712.09 ÷ 342,882,536

= $116,954.05 a person

× 4 people = $467,816

$94,499 a person is held by the public, $22,455 by trust funds

Of the total, $32.40 trillion is debt held by the public: Treasury bills, notes and bonds owned by investors outside the federal government. The other $7.70 trillion is intragovernmental: securities held by federal trust funds such as Social Security’s.

Economists usually focus on debt held by the public, because it is what the government borrows from markets and pays interest to outsiders on. Intragovernmental debt is money one part of the government owes another.

A share of the debt is not a bill anyone owes

Nobody receives an invoice for $116,954. The debt is owed by the federal government to the holders of its securities, and it is serviced from federal revenue and by issuing new securities as old ones mature.

The per-person figure is a way to picture the size of the debt, not a measure of what any household will pay. Taxes, spending and economic growth decide how the burden is actually shared.

Per person and per dollar of output answer different questions

Debt per person grows with the debt and shrinks with population. Debt as a share of GDP compares it with the economy that supports it, which is the measure most often used to judge whether a debt is sustainable.

Use the debt-to-GDP ratio calculator for that comparison. The two views together show both how big the debt is for each person and how big it is against what the country produces.

Two official figures, each with its date

The debt comes from Treasury’s Debt to the Penny dataset, which reports total public debt outstanding, debt held by the public and intragovernmental holdings for each business day. The population comes from the Census Bureau’s population clock, a running estimate.

The figures on this page are as of the dates shown. Both move every day, so the share per person moves with them.

Worked example

The debt on September 18, 2026 and the population on September 22, 2026.

Worked example

Total public debt = $40.10 trillion

US population = 342,882,536

Per person = $116,954

Held by the public, per person = $94,499

Household of four = $467,816

Limitations

  • The share is an average across everyone, including children; it is not a bill any person owes.
  • The debt figure changes every business day; the page shows the date it was read.
